Abstract

As the population of P2P networks increases, service differentiation issues become very important in distinguishing cooperating peers from free-loaders. The basis for service differentiation could either be economic or the fact that the peers differ from each other in the type of services and resources they contribute to the system. Taking the latter approach, this paper makes three contributions: 1) it defines parameters that are suitable for service differentiation in P2P networks, 2) it proposes SDP, a protocol to accomplish service differentiation, and 3) it identifies a set of features that are necessary in a reputation system that measures the contributions of individual peers in the system.
